People do shaft Goff with regard to throwing on the run. Compared to the rest of his game, it's a weakness. But he's not bad at it. He's just not amazing at it like he is throwing from the pocket.
Yes it was a big weakness last year particularly, his accuracy dropped noticeably on the run but also when he's moving more than a shuffle. This year he's actually improved a lot at it, but yes and it's one of the examples of how the Goff we see now isn't the guy we're going to have a couple years from now.
He's already one hell of a QB but he has plenty of room to improve. I want to see him get better at throwing under pressure too. He's got the ability to throw in the face of the blitz, but his accuracy in those situations is where he can improve the most.
